Removal of elemental mercury (Hg0) with the reactive species produced from dielectric barrier discharge (DBD) was studied. We investigated the effect of operating parameters such as the applied voltage, residence time, initial concentration and co-existence of other pollutants. The removal of Hg0 was significantly promoted by an increase in the applied voltage of the DBD reactor system. It is important to note that at the same input power, the removal efficiency of Hg0 was much higher than that of NO gas. These results imply that if the DBD system is used as a NOx treatment facility, it is capable of removing Hg0 simultaneously with NOx.
